Objective: To develop a new screen for asthma and allergies based on the BPAS (BPAS ) with the intent of keeping the screen brief and simple, while including allergy detection.
Methods: Questions from the BPAS were extensively revised, and questions regarding allergic rhinitis were added. A panel of parents of asthmatic children reviewed and critiqued the questions. The final BPAS was distributed in elementary schools, and a cohort of 129 participated in a validation against the gold standard of evaluation by an expert in asthma.
Results: For asthma the best items were wheeze, persistent cough, night cough, and response to change in air temperature. The simplest scoring, any 1 of the 4 items, yielded the best balance of specificity (73.6%) and sensitivity (73.3%). For allergy, using all six items, having any one or any two of the items had sensitivity of 71.4% and specificity of 77.3%.
Conclusions: The BPAS provides a rapid and valid method for the detection of potential allergy and asthma in schoolchildren. Sensitivity and specificity are acceptable for both asthma and allergies.
